Math.Sin is returning different values than the Windows Calculator

Posted 20 September 2013 - 03:09 AM

Hello DreamInCode Members,

I have made a Windows Form Application Calculator and have been testing as I go along with the actual Windows Calculator, but when I finished the "Sin" button, the results were always different than the regular Windows Calculator's results. Not sure why they are different, was hoping someone here could offer me some guidance.

Thank you in advance,

For example, with my calculator "Sin(25)" comes out to -0.132351750097773
But with the Windows Scientific Calculator "Sin(25)" comes out to .4226182617406......
